CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of and is a continuation in part of U.S. Nonprovisional patent application Ser. No. 14/627,442, filed Feb. 20, 2015 and incorporated herein by reference in its entirety.

BACKGROUND

Perspiration under the arm can be very uncomfortable and embarrassing for most people. Depending on the level of perspiration, one can simply stain and ruin clothing from sweating. The options to remedy excessive sweating under the arm are limited, instead particularly to two primary solutions; antiperspirant and deodorant.

Antiperspirant contains a form of aluminum compound that when applied to the underarm, only partially blocks the sweat glands, ineffectively barring the ability to sweat. Furthermore, applying antiperspirant multiple times can potentially damage the sweat ducts.

Deodorant is more like perfume for the armpits. It is not intended to reduce the production of sweat, but created to only mask the body odor. Some deodorants may become immune to the skin if one uses the same brand for years, possibly causing odorous bacteria.

People often sweat when there is emotional instability. These problems may arise during occasions that causes one to be extremely nervous, anxious, and/or stressed. For instance, a job interview or first date would cause one to be apprehensive which in turn causes perspiration. Having an excessive amount of sweat underneath the arm is unattractive and quite embarrassing that causes an odor.

Profuse sweating is likely to soil a shirt leaving a stain in the underarm region of the garment. Few shirts come with sweat pads pre-installed in the shirt itself. This requires additional shirt material, which traps more heat, causing more sweat.

SUMMARY

The present inventor has recognized the armpit area is a unique surface with unique challenges that the present art does not address. The disclosed article may not only reduce or eliminate sweat stains, but also capture sweat by way of the article's attachment to the skin of the wearer in the area corresponding to a human armpit.

Embodiments relate to an article adhesively attachable to at least a portion of the skin surrounding a user's armpit, the article having a first surface facing the body of a user and at least a second surface aligned approximately opposite the first surface. The article is a cruciform shaped article comprising a centrally located absorbent padding exposed on at least the first surface of the article.

The cruciform shape of the article means that it has at least four arms radiating from a central portion of the article. These arms are a top arm, bottom arm, and two side arms. The top arm is adapted for adhesive attachment to the skin in a location approximately corresponding to skin covering a human coracobrachialis. The bottom arm is adapted for adhesive attachment to the skin in a location approximately corresponding to skin covering a human serratus anterior. The two side arms are adapted for adhesive attachment to the skin in a location approximately corresponding to skin covering a human pectoralis major and a human teres minor, respectively. Other embodiments of the article are envisioned as detailed in the detailed description below, the disclosure of which is incorporated in this Summary.

Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. Moreover, all ranges disclosed herein are to be understood to encompass any and all sub-ranges subsumed therein. For example, a range of “less than 10” can include any and all sub-ranges between (and including) the minimum value of zero and the maximum value of 10, that is, any and all sub-ranges having a minimum value of equal to or greater than zero and a maximum value of equal to or less than 10, e.g., 1 to 4.

Disclosed is an article 10 which is applied to the skin in and around the armpit so as to absorb perspiration. The article further serves to protect the user's clothing from unseemly staining. The article is adapted for use by individuals suffering from excessive sweating for which traditional deodorants or antiperspirants prove ineffective.

Broadly, the article 10 has a first surface facing the body of a user and at least a second surface aligned approximately opposite the first surface. The first surface is also referred to as the “skin facing surface” and is the side shown in the view of FIGS. 1 and 2 (assembled and exploded views, respectively). The second surface of the article is the side that faces the user's garment when the article is worn underneath clothing. The exploded view of FIG. 3 shows the second surface.

The article 10 is a cruciform (cross shaped) article preferably having four arms which are communicably connected at a central portion 12, which is a generally central portion of the assembled article making up the area in and surrounding the intersection of axes 34, 36, and 38. These four arms comprise a top arm 24 and a bottom arm 26. The top arm 24 is shorter than the bottom arm 26 in an embodiment. There are also two side arms 28 a, 28 b, which are of equal length in an embodiment.

The article 10 is adapted for placement directly on a user's skin, as shown in FIG. 4. The central portion 12 on the skin facing surface is adapted for absorbing perspiration and wicking moisture away from the user's skin. In the embodiment of FIGS. 2-3, this may be accomplished by configuring the article in three layers. FIG. 2 is an exploded view of the article of FIG. 1. FIG. 2 shows a backing layer 14 and a top layer 16 adapted for communication with one another. An absorbent padding 18 is sandwiched between the backing layer 14 and the top layer 16 when the article is assembled, as shown.

The backing layer 14 may be a planar, thin, substantially flat (less than 2 mm thin) surface having the aforementioned cruciform shape. The top layer 16 may have the same cruciform shape as backing layer 14, but modified so as to receive the absorbent padding 18. This may be accomplished in the embodiment shown by a raised portion 22 in the location corresponding to the central portion 12. This raised portion 22 is a raised platform with a recess underneath. The absorbent padding nests in the raised portion 22 such that the raised portion 22 conforms to and surrounds the absorbent padding 18. (FIG. 3 shows that the absorbent padding 18 lying in the recess of the raised portion, flush with the second surface of the top layer. In the embodiment shown, the raised portion 22 is raised 2.5 mm above the plane of the four arms so as to accommodate an absorbent padding 18 that is 2.5 mm thick. The raised portion 22 has an opening 20 from which the underlying absorbent padding 18 may be exposed to the skin facing surface (as can be seen in FIG. 1). This opening 20 may also be cruciform in shape, with proportions corresponding to the proportions of the article's overall cruciform shape. The opening 20 may also be circular or oval in shape.

The design pictured shows the absorbent padding 18 may be larger than the opening 20. By having the absorbent padding 18 larger than the opening 20, moisture is first absorbed at the portion of the absorbent padding 18 exposed by the opening 20. That moisture then migrates outwards in a radiating fashion so as to fill the absorbent padding 18 by diffusion of the fluid across absorbent padding's absorbent surface. This way, moisture is drawn under the raised portion 22 of the top layer 16 and a significant portion of the absorbent padding 18 is not directly exposed therefore to the user's skin. This aids in the comfort and overall dryness of the article when worn because this configuration aids in keeping the moisture away from the user's skin.

The absorbent padding itself may be made from fibrous absorbent materials, tissue, or other absorbent materials known in the art including foam, cotton (cellulose fibers), fabric, or other fabric or fibrous netting, whether in a single or multiple layer configuration. The absorbent padding 18 may also incorporate anhydrous materials adapted to absorb moisture, such as sodium sulfate or other desiccants, preferably incorporated in portions not exposed to skin due to possible skin irritation—one location for such materials would be in the portion of the absorbent padding 18 located underneath the raised portion 22.

The three layers may communicate with one another by means known in the art. In one embodiment, the backing layer 14 is a clear, flexible material resistant to ripping and skin irritation, such as silicone, having a bonded adhesive on its skin facing surface. This adhesive permits the top layer to lie down on the backing layer (such that the absorbent padding is sandwiched between the layers) so as to form a seal around the perimeter of the absorbent padding 18. Alternatively, the top layer can be coated with adhesive on its second surface bonding to the backing layer, or both the top and backing layers are coated at least in part with an adhesive.

Other embodiments may join the components of the article differently. For example, the adhesive may be applied after the absorbent padding 18 is laid atop the backing layer 14 during manufacture, allowing the adhesive to be applied in those portions of the backing layer 14 not covered by the absorbent padding. The top layer 16 may then be laid atop the absorbent padding 18, so that it adheres to the backing layer 14 only where the adhesive has been applied, allowing the absorbent padding to “float” within the raised portion 22. This configuration also improves breathability and circulation throughout the article 10. The absorbent padding 18 may also be adhered to the backing layer as well, but this is not required, as the absorbent padding 18 will remain in place underneath the raised portion 22 without the absorbent padding's 18 having to be bonded to the backing layer 14. Alternatively, the top layer 18 itself may be have an adhesive on its second surface for bonding to the backing layer 14. An example adhesive for bonding the components to themselves is cyanoacrylate adhesive.

It should be noted that the article is adapted for use by a user in the underarm area. The article must then be adapted for attachment, either fixedly or removably, to a user. For this end, the article may have a medical grade tacky substance coated on all or a part of its skin facing surface. Alternatively, the top layer itself may be constructed in whole or in part of a sticky silicone, silicone gel, silicone paste, or other tacky substance for attaching an article to skin firmly. The embodiment using silicone gel is preferred, as it is removable without discomfort and provides a gentle but firm adhesion to the skin. Other adhesives known in the art for attaching an article to skin firmly may be employed. The

If the means for adhering the article to the user's skin comprises adhesive coated on all or a portion of the skin facing surface of the top layer, the coating may be perforated or applied only in portions of the skin facing surface of the top layer 16. One embodiment, as shown, depicts a quadrangular adhesive tab 30 a,b,c,d (collectively the “tab” or “tabs”), located on each arm of the article. Other shaped adhesive areas may be used. All or any portion of the top layer 16 may comprise similar types of adhesive for bonding the article 10 to the user's skin, and various shaped tabs may be employed. The adhesive of the tabs must be non allergenic, and dermatologically acceptable, which means that after continuous contact with the skin there is little or no adhesive residue or skin irritation upon removal, or while adhered to the skin. The adhesive of the tabs may be topped with medical grade paper to protect the adhesive when the article is not in use.

The cruciform shape of the article is suited for the particular anatomy of the underarm. The human underarm is subject to forces present with the single ball and socket joint movement of the arm about the torso. The article's four arms and cruciform shape accommodate the unique forces present in this area of the human anatomy. The inventors have determined one of the largest moving force against the article is in the location just below the armpit. Also, as perspiration would tend to gravitate down the body, the article is designed to provide additional support in the area of the bottom arm 26. The inventors have also recognized that although it would seem perspiration would tend to all migrate downward due to gravity, a cruciform shaped opening 20 as well as a large absorbent pad is better able to capture perspiration that can travel generally horizontally in the seam of the arm. The article has therefore been designed so as to capture moisture travelling in both general directions.

For an adult human, the article may be between 6 and 9 inches along the line of symmetry of the longitudinal axis 34 and between 5-7 inches in length on the longest portion of its horizontal axis 36 (the axis bisecting the side arms 28 a.b). Each arm has a narrow, tapered neck 32 a,b,c,d, as depicted. The bottom arm 26 is preferably longer than the top arm 24. The bottom arm may be 3 inches wide at its widest point and 2.5 inches wide at the neck 32 b. The side arms have a necks 32 a,c, which are narrower than the neck 32 b of the bottom arm 26. The location where the arms join the central portion are narrowed, in such a way that the arms can be described as having a head and neck configuration, the neck serving to join the arm to the central portion. The bottom arm preferably has a wider neck relative to the “head” of the arm. The edges of the arms are curved as shown, aiding in the comfort and conformance of the article with the user's skin in the general armpit area. The arms may be configured with right angle turns in an embodiment.

FIG. 4 shows the article in use on a user. In an embodiment, the bottom arm 26 is the bottom arm of a Christian cross and attaches via tab 30 b on the skin approximately corresponding to the skin covering a human serratus anterior muscle. The top arm 24 attaches via tab 30 d on the skin approximately corresponding to the skin covering a human coracobrachialis. Side arms 28 a,b attach to the skin via tabs 30 a and 30 c in the area arm corresponding to the skin covering the pectoralis major and the lattisimus dorsi, respectively.

As used in this disclosure, the term “approximately” as it relates to the position of the arms when the article is worn shall mean that the arms are located on skin corresponding to skin covering the muscles described within a range covering adjacent muscles. For instance, the side arm 28 a, which attaches to the skin in the area corresponding to the pectoralis major can also extend so as to attach to skin covering an adjacent muscle, such as the pectoralis minor or the serratus anterior. The side arm 28 b, which attaches to the skin in the area corresponding to that which covers a human teres minor muscle similarly may extend to skin covering the teres major or to the skin covering the lattisimus dorsi (the portion of the lattisimus dorsi located on a human back). The bottom arm 26, which attaches to the skin in the area corresponding to that which covers the serratus anterior muscle may also extend to skin covering the adjacent serratus anterior and/or lattisimus dorsi muscles.
